Trigger movies simultanously

Hi! I am trying to play 3 movies at the same time on the same computer. And I would like to trigger them with MaxMSP. If I play them in Max with jit.qt.movie, CPU gets very high and they start bucking.
If I play them in QuickTime it works fine. Just how to communicate from Max to Quicktime?

I tried applescript with the shell, aka-shell and taptools.
The taptools helpfile looks fine, just: there is no taptools.mxo inside the bundle.
For shell and aka-shell I don’t know the commands to run the applescript.
